Some observations that I wanted to share. I'm in the habit of uploading my BMPCC 1080p footage in Ultra HD 4K on YouTube, using QuickTime as a wrapper and DNxHR HQ as a codec when creating a render in the Delivery page of DaVinci Resolve.

When doing that render in Resolve 12.5.3, although it took all day to do the upload, I succeded using Firefox (my preferred browser). But after upgrading to 12.5.4 YouTube crashed on me after less than 30 minutes on each try, regardless of the size of the file. It only accepted 1080p HD.

I have made several attempts for the past weeks to no avail. My brilliant son came up with the idea to switch to Google Chrome, thinking that as YouTube nowadays is an extension of Google it could perhaps be more compatible. I tried it out starting yesterday. And it didn't crash.

So the conclusion is that, regardless if Resolve 12.5.4 has some issues with uploading Ultra HD 4K to YouTube or not, it is obvious that Google Chrome is a more stable browser compared to Firefox when you want to upload Ultra HD to YouTube. Don't know how Explorer works out but I generally dislike it as a universal browser.

If you have any comments or observations that corroborates mine, or disproves them, please share them here.

Yeh I used Chrome exclusively. But in my opinion, uploading a 4k DNxHR HQ file is just 2 much of a pain in the ass to upload timewise for a minuscule quality bump on youtube. But obviously if you have a blazing fast connection that is a different story.

I understand, especially in different countries, bandwidth is different from house to house but my FiOS 150/150 plan is really really nice. I get better transfer speeds than some of my USB2 flash drives.

It took me approx 17 hours to upload 15 minutes of footage. I believe it had a faster ratio than with my previous (successful) upload of 17 minutes footage that took more than 30 hours with Firefox. So it seems that Google Chrome is faster as well.
